Singular or plural for enumerations?

Question

Do you use singular or plural for enumerations? I think it makes best sense with plural in the declaration

enum Weekdays
{
    Monday,
    Tuesday,
    Wednesday         


        

Answer 1

One recommendation comes from the .NET Framework Design Guidelines, page 59-60:

Do use a singular type name for an enumeration, unless its values are bit fields.

public enum ConsoleColor {
  Black,
  Blue,
  Cyan,
  ...

Do use a plural type name for an enumeration with bit fields as values, also called a flags enum.

[Flags]
public enum ConsoleModifiers {
  Alt,
  Control,
  Shift
}
